St. Louis Astronomical Society Meeting - Mapping Millions of Galaxies and Quasars - The Sloan Digital Sky Survey

An illustrated presentation by Larry Bartoszek of Bartoszek Engineering

Mr. Bartoszek is an Illinois Licensed Professional Engineer and owner of Bartoszek Engineering. His consulting firm specializes in the design of nuclear and high energy physics facilities, both here and abroad. Mr. Bartoszek worked at the Fermi National Laboratory from 1983 to 1993. While there, among many projects involving sub-atomic particle accelerators, he designed the pneumatic latches that hold the $4 million dollar CCD camera and the spectroscopes to the bottom of the SDSS telescope.

The Sloan Digital Sky Survey (SDSS) uses a new telescope at Apache Point Observatory near Alamagordo, New Mexico to map the night sky in great detail. It produces both regular images and spectra – starlight and galaxy-light spilt into their component colors. It does its mapping with a 120 megapixel digital camera and two spectrographs. SDSS has created a three dimensional map of the sky with a million galaxies and quasars. Mr. Bartoszek will discuss the Survey and explain how data collected by SDSS has provided insights into dark matter and dark energy, as well as visible galaxies and quasars.  All of the SDSS data is available on the web, for use by amateur and professional astronomers and the general public. 

The St. Louis Astronomical Society is an organization for individuals interested in astronomy and telescopes. The public is invited to attend its meetings, telescope observing sessions, and special events. For more information about Astronomical Society events, please visit www.slasonline.org or call 314- 962-9231.  The event, cosponsored by NASA's Missouri Space Grant Consortium at Washington University, is open to the public free of charge.
